In case of fire, the main cause of most casualties is not burning but suffocation by toxic gases and smoke.
Escape Guide is a unified rescue system, which saves people in public spaces by light, sound, and gas masks. When a fire detected, the wall mount facility illuminates the space, makes alarm, and releases self-generating flashlights, which hold several gas masks. It also projects a pathway to an exit on the floor to make people bend down and escape safely. Therefore some people take the flashlights first, then distribute the gas masks to others nearby and lead the groups to the exit.
